Protective visor for marine electronics

ABSTRACT

A visor shield for shielding a marine electronic device from sunlight, weather and spray includes a visor body having a base portion for attachment to an electronic device, and a protruding portion extending from the base portion and sized to extend out from the electronic device to shade a front face of the electronic device. The base portion and the protruding portion can be formed of a unitary plastic part. The base portion can comprise a wall continuous with the protruding portion. A compressible seal can be attached to a surface of the wall and arranged to be compressed against a housing of the electronic device when the base portion is attached to the electronic device.

This application claims the benefit of U. S. provisional patent application Ser. No. 60/761,494 filed Jan. 24, 2006.

BACKGROUND OF THE INVENTION

Marine electronics with display screens, for example, depth sounders, fish locators, global positioning satellite (GPS) systems, chart plotters, navigation displays, or radar displays, are difficult to view in direct sunlight.

Also, prolonged ultraviolet light (UV) and weather exposure can deteriorate the electronic device.

Also, when a boat is under forward power, with the electronic device facing the driver, rain and sea spray can accumulate on the screen making viewing difficult.

Hinged visors have been used to shield glare and ultraviolet light from laptop computers. The hinge design is not applicable for outdoor use when weather protection is needed.

Glare reduction filters are available for liquid crystal diode (LCD) screens. The benefits of the screen are reduced when viewed through polarized lenses. polarized sunglasses are commonly worn during marine use.

The present inventor has recognized the need for a device to protect electronic devices used on boats or other marine equipment, particularly a device that protects displays and controls from ambient conditions.

SUMMARY OF THE INVENTION

The present invention provides a protective visor to protect electronic devices from weather and other ambient conditions. The present invention provides a protective visor that reduces glare on display screens of electronic devices. The present invention provides a protective visor that reduces ultraviolet exposure to keypads and display screens of electronic devices. The present invention provides a protective visor that protects the view of a display screen of electronic devices against rain or water spray condition when the boat is under forward power. The present invention provides a protective visor that is adaptable to be removable or permanently attached.

According to a preferred embodiment, a visor shield for a marine electronic device includes a visor body having a base portion for attachment to an electronic device, and a protruding portion extending from the base portion and sized to extend out from the electronic device to shade a front face of the electronic device. The base portion and the protruding portion can be formed of a unitary plastic part. The base portion can comprise a wall continuous with the protruding portion. A compressible seal can be attached to a surface of the wall and arranged to be compressed against a housing of the electronic device when the base portion is attached to the electronic device.

The base portion and the protruding portion comprise a U-shaped cross-section. A removable attachment can be arranged between the base portion and the electronic device. The removable attachment can be a hook strip configured to be applied to one of the electronic device and the base portion, and a corresponding loop strip configured to be applied to the respective other of the electronic device and the base portion.

Numerous other advantages and features of the present invention will be become readily apparent from the following detailed description of the invention and the embodiments thereof, and from the accompanying drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

While this invention is susceptible of embodiment in many different forms, there are shown in the drawings, and will be described herein in detail, specific embodiments thereof with the understanding that the present disclosure is to be considered as an exemplification of the principles of the invention and is not intended to limit the invention to the specific embodiments illustrated.

FIGS. 1 and 2 show a visor shield 20. Preferably, the visor shield 20 is composed of a unitary piece of plastic material, such as KYDEX® T thermoplastic sheeting, available from Kleerdex Company, LLC of Bloomsburg, Pa., USA. Alternately, ABS or PVC plastic materials could be used. Preferably, the shield 20 includes a base portion 24 and a protruding portion 25 including a turn-up facing edge 26. The edge 26 extends across a top of the shield, and on opposite sides for a length L which is one half to two thirds of a height H of the visor shield 20. The visor shield 20 is shown mounted to a typical marine electronic device 28, having a display screen 28 a and controls 28 b. The base portion 24 of the visor shield 20 closely fits over a portion of the electronic device 28 and is configured for attachment thereto. The visor shield 20 is attached to the electronic device 28 by removable attachments 34, 35. Preferably, the removable attachments comprise hook and loop surface attachment components. For example, a strip of hooks 34 could be attached to the visor shields 20 and a strip of loops 35 could be attached to the electronic device 28, or vice versa. The strips 34, 35 could be permanently attached to the respective component 20, 28 and the interface between the strips 34, 35 can be made removable by forcibly breaking the grip between the hooks and loops.

Alternatively, the visor shield 20 can be fastened to the electronic device 28 or adhesively secured thereto.

As illustrated in FIG. 2, when a marine craft is propelled through the water in the direction A, sea spray or precipitation is driven against a backside of the electronic device and visor shield 20 in the direction W. The turned edge 26 directs the water away from the electronic device, either outwardly or downwardly.

As shown in FIGS. 3 and 4, a compressible weather resistant gasket 40 runs continuously along an edge of the base portion 24 of the visor shield 20. The gasket 40 prevents water from seeping between the visor shield 20 and the electronic device. Preferably, the gasket is a 3/16″ height, adhesive backed neoprene/EPDM/SBR foam rubber strip.

From the foregoing, it will be observed that numerous variations and modifications may be effected without departing from the spirit and scope of the invention. It is to be understood that no limitation with respect to the specific apparatus illustrated herein is intended or should be inferred.
